§ 02 · Hazards identification

Harmonised EU classification

CLP Annex VI · Index 601-020-00-8. A supplier SDS may add self-classified hazards — this is the legal minimum.

H225 Highly flammable liquid and vapour. Flammable liquid — Category 2 (Flam. Liq. 2)
H304 May be fatal if swallowed and enters airways. Aspiration hazard — Category 1 (Asp. Tox. 1)
H315 Causes skin irritation. Skin irritation — Category 2 (Skin Irrit. 2)
H319 Causes serious eye irritation. Eye irritation — Category 2 (Eye Irrit. 2)
H340 May cause genetic defects. Germ cell mutagenicity — Category 1 (Muta. 1)
H350 May cause cancer. Carcinogenicity — Category 1 (Carc. 1)
H372 Causes damage to organs through prolonged or repeated exposure. STOT repeated exposure — Category 1 (STOT RE 1)

§ 13 · Disposal considerations

Dispose of waste and residues in accordance with local and national regulations — in the EU under the Waste Framework Directive 2008/98/EC. Never discharge to drains or municipal waste; hand contaminated packaging and unused product to an authorised waste-disposal company. The supplier's SDS section 13 lists the applicable waste codes for the specific product.

MSDS vs SDS

MSDS vs SDS: is there a difference?

MSDS (Material Safety Data Sheet) is the older name for the same document. In the US, OSHA's Hazard Communication Standard (2012) adopted the GHS-standardised 16-section Safety Data Sheet; in the EU the format is set by REACH Annex II. So a "benzene MSDS" and a "benzene SDS" refer to the same document — today it is issued as an SDS. Full breakdown of the differences →

§ 16 · Sources

Reference aid only. This page summarises the harmonised EU classification and computed storage guidance — it is not a Safety Data Sheet and does not replace one. Always verify hazards, handling and storage against the supplier's SDS (sections 7 and 10) and local regulations before use. Page updated 2026-07-27.

Frequently asked questions

Is an MSDS the same as an SDS?

In practice, yes. MSDS (Material Safety Data Sheet) is the older name for the same document. In the US, OSHA's Hazard Communication Standard (2012) adopted the GHS-standardised 16-section Safety Data Sheet; in the EU the SDS format is set by REACH Annex II. A document you find labelled "benzene MSDS" is today issued as an SDS.

What GHS pictograms does benzene require?

Under the harmonised EU classification (CLP Annex VI), benzene carries GHS02 and GHS07 and GHS08 with the signal word "Danger". Hazard statements: H225, H350, H340, H304, H372, H315, H319. A supplier's SDS may add self-classified hazards on top of this harmonised minimum.

What should benzene never be stored with?

Based on its storage class (Flammable liquids), benzene must not share storage with: Organic peroxides & self-reactives; Oxidizing acids; Oxidizers. Verify against the supplier's SDS sections 7 and 10 before finalising storage.

Where can I download an official benzene SDS PDF?

From your own supplier — an SDS is issued per product and supplier, so the correct PDF for an inspection is the one matching the product you actually purchased. The supplier links on this page lead to the official SDS libraries of major distributors.
